Organic electroluminescent display panel

Abstract

An organic electroluminescent display panel includes a substrate that includes a display panel region having a plurality of organic electroluminescent devices each including a plurality of display electrodes and an organic material layer, which are stacked, and electrically conductive connecting lines electrically connected to electrodes formed in a domain surrounding the display panel region on the substrate. The connecting lines are lower in resistance than the electrodes formed on the display panel region.

What is claimed is:  
     
       1. An organic electroluminescent display panel comprising: 
       a substrate including a display panel region having a plurality of organic electroluminescent devices each formed of a plurality of display electrodes and an organic material layer, which are stacked; and  
       a plurality of electrically conductive connecting lines electrically connected to said electrodes formed in a domain surrounding the display panel region on said substrate;  
       wherein said connecting lines are lower in resistance than said electrodes.  
     
     
       2. The organic electroluminescent display panel according to  claim 1 , wherein said connecting lines are constituted by electrically conductive thick portions that are thicker than said electrodes. 
     
     
       3. The organic electroluminescent display panel according to  claim 1 , wherein the surface area of the connecting lines is larger than said electrodes. 
     
     
       4. The organic electroluminescent display panel according to  claim 1 , wherein said connecting lines are made of a material that is lower in resistance than a material of said electrodes. 
     
     
       5. The organic electroluminescent display panel according to  claim 2 , wherein a total thickness of said connecting lines and said thick portions is larger than a film thickness of said electrode provided on a topmost surface. 
     
     
       6. The organic electroluminescent display panel according to  claim 2 , wherein said thick portions are made of the same material as said connecting lines.
